As far as I can tell it may have fixed the problem. It just built for
me on a fresh bootstrap of pkgsrc-current on solaris 10 x86 w/gcc (32
bit).

I was able to build the package unmodified. But I recommend adding my
patch anyway, because it is a waste of time to compile examples (that
according to the upstream documentation are bound to fail), and then
throw them away. And as a personal bonus: The dependencies seem to have
changed and I don't even need this package anymore...
